What is the prerequisite action an operator must take before conducting a breath test?

Before conducting a breath test using the Intoxilyzer 8000, it is essential for the operator to confirm that the subject has not consumed anything for at least 15-20 minutes. This critical step ensures that the test results are accurate and not influenced by any substances that may have been recently consumed, such as food or beverages, which can interfere with the measurement of blood alcohol content (BAC).

During this waiting period, known as the observation period, the operator monitors the subject to ensure they do not engage in actions like eating, drinking, or regurgitating, as these could lead to misleading test results. Proper adherence to this prerequisite helps to maintain the integrity of the testing process and supports the validity of the outcomes.

Other actions, such as ensuring the device is charged or checking its calibration, are also important for the overall accuracy and functionality of the testing equipment but do not address the immediate necessity of controlling the conditions of the subject prior to taking the breath test.
